Product Name: API 6D Trunnion Mounted Ball Valve
Design Standard: API 6D
Body Material: ASTM A216 WCB
Size: 4 Inch, DN100
Pressure: Class 600 LB, PN100
End Connection: RF
Operation: Gearbox
Trunnion Mounted Ball Valves are designed for smooth operation under high line pressure. The ball is fixed in position yet free to rotate, with carefully aligned bearings ensuring low torque operation.
All Cast Trunnion Ball Valves are crafted from high-quality castings and feature a fire-safe design, certified according to BS 6755, API 607, and API 6FA, meeting all applicable ASME standards.
Cast Steel Trunnion Ball Valves are available in Two-Piece Split Body and Three-Piece Bolted Body types. They are designed and manufactured to the latest international standards, including API 6D, ASME B16.34, BS 5351, or equivalents. Standard features include Fire-Safe, Anti-Static, and Stem Blow-out Proof design.
